Thanks for the help Chicane!!

Should have some pics thrown up to this thread in a couple of days once I get the trailing arms put in place.

thanks again!!

Well, here are a few shots of the suspension tacked into place so I can find the optimum location for the camber bar. Oddly enough, I get the best results with the camber bar located right under the half shaft....getting just a little over a degree positive camber in rebound, and a little over 1.5 degree negative in bump.

Using .120" plate for the boxes for the trailing arms, and the boxes will be just that -- fully boxed on the inboard side with gussets top and bottom on the outboard side.

Thoughts? Something tells me that .120" is too light for mounting the trailing arms, but the main tubes are .120" wall for the chassis, and these will be fully boxed sections, not just three pieces of sheet tacked together.

I'm trying to set up the right and left side of the suspension -- am running into a slight problem. The toe rod sits slightly different from right to left. On the left side, the toe rod sits a little further away from the diff than on the right side.

Chicane -- you mentioned the '88 change on the knuckles for better bump steer -- would you (or anyone else looking at this thread!) happen to know part numbers for the knuckles?? I have:

Left -- 20052209 (can't find this anywhere)
Right -- 10270127 (this checks on gmpartsdirect.com as a valid 1995 part)

The rear suspension is supposed to be from a 1995 MY car...looks like I might have mixed parts???


thx,

Actually found TWO P/N's for the rear knuckles for the post-'88 C4 Suspension:


L: 10270126 OR 10052209

R: 10270127 OR 10052210

It looks like I have L = 10052209 and R = 10270127. They are similar, but the hole for the ball joint is in a slightly different location on each.
